Will Labour Party win the most seats in the New Zealand House of Representatives in the 2026 New Zealand legislative election?

As of November 4, 2026, Polymarket prices “Will Labour Party win the most seats in the New Zealand House of Representatives in the 2026 New Zealand legislative election?” at 33% YES with $53K traded. No tracked wallet holds a position on this market, so there is no verdict.

Labour currently holds 34 of 123 seats versus National's 49, and polling trends favor National, so Labour is unlikely to win the most seats in 2026.

What’s Happening

The 2026 New Zealand legislative election is set for November 7, 2026, with early voting already under way, and the question of whether the Labour Party can win the most seats in the New Zealand House of Representatives remains open. A Roy Morgan poll published October 6, 2026 showed the National-led government widening its lead over the Labour-led opposition to 52% versus 41.5%, with Labour's party vote at 23.5% — below its 26.9% result in 2023. Under New Zealand's mixed-member proportional system, a party must clear 5% of the party vote to enter Parliament, and seats are allocated proportionally, meaning Labour would need to overtake National in the party vote to win the most seats.

The race has been volatile. A September 15, 2026 RNZ report on a new poll found both major parties below the 30% mark with less than two months until the election, projecting a possible hung parliament with the coalition bloc and opposition bloc tied at 60 seats each. An August Roy Morgan survey had National-led government support at 49% against Labour-led opposition at 41%, with the Opportunity Party rising to a record 9.5%. The fragmentation of the minor-party vote — including ACT at 11% and NZ First at 10% in September — complicates any path for Labour to win the most seats in the New Zealand House of Representatives, since opposition parties would need to consolidate behind Labour.

Electorate-level contests could prove decisive. The Spinoff's November 2, 2026 ranking of every electorate race noted that boundary changes have shifted seats such as Tangi Utikere's electorate to the right, potentially tightening races Labour previously held comfortably, while Banks Peninsula — the birthplace of the Labour Party — is an open race following Damien O'Connor's move to Waitaki. With advance voting under way and the final result due after November 7, the outcome will hinge on whether Labour can lift its party vote above National's and convert electorate gains into a plurality of seats.
